Updating UTextRenderComponent in C++ in Editor

Hi,

I’m trying to update a UTextRenderComponent component in code based on variables set by designers.

I’m registering to the selection callback as so:
USelection::SelectObjectEvent.AddUObject(this, &MyClass::OnObjectSelected);

void MyClass::OnObjectSelected(UObject* Object)
{
	if (TextRenderComponent == nullptr)
	{
		TextRenderComponent = FindComponentByClass<UTextRenderComponent>();
	}

	if (Object == this)
	{
		if (TextRenderComponent)
		{
			// Convert Enum into Text
			FString flags = GetStringFromDesignerFlags();
			FText string = FText::FromString(flags);
			TextRenderComponent->SetText(string);
		}
	}
	else
	{
		if (TextRenderComponent)
		{
			FText string = FText::FromString("");
			TextRenderComponent->SetText(string);
		}
	}
}

Unfortunately this only updates once and afterwards fails to update on subsequent selections.

it looks like it’s failing in:
void UActorComponent::MarkRenderStateDirty()

as bRenderStateCreated is false.

Can you shed any light on this please?

Cheers,
Chris
